The door structure 100 includes a door inner panel (hereinafter also simply referred to as an inner panel) 10 and a door module 20 arranged to cover an opening (not shown) of the inner panel 10 from the outside of the vehicle.

The door module 20 includes a resin-made door module panel (hereinafter also referred to simply as a module panel) 30, and various functional parts such as a door lock mechanism (door latch mechanism) 40, a door opening/closing mechanism, and a window glass lifting mechanism are arranged. It is a thing. Note that functional parts other than the door lock mechanism 40 and cables connected thereto are omitted from the illustration for the sake of simplification.

The door module 20 is attached to the inner panel 10 from the outside of the vehicle while the door lock mechanism 40 is arranged on the outside of the module panel 30 .

The door lock mechanism 40 is interlocked with a pair of cables (latch wires) 50 connected to an operation portion (not shown) arranged inside the vehicle, and engages an engaging portion (not shown) provided at the entrance of the vehicle. ) to lock or unlock the door. Since the door lock mechanism 40 has a conventionally well-known structure, a detailed description thereof is omitted, and the illustration thereof is also schematic.

To prevent water from entering through the opening of the inner panel 10 and splashing on various functional parts arranged inside the vehicle when the door module 20 is attached to the inner panel 10. Secondly, between the outer surface of the inner panel 10, the inner surface of the module panel 30, and the inner and outer surfaces of the module panel 30, the coating is applied in a band shape on the entire periphery of the module panel 30 except for a part of the section. A sealing portion 60 formed by solidifying a sealing agent (adhesive, sealer) is interposed. This partial section is a partial section of the upper edge of the module panel 30 and a section where the gap S through which the cable 50 passes is located.

The cable 50 has one end connected to the rear portion of the door lock mechanism 40 and extends rearward from the door lock mechanism 40 . The cable 50 extends rearward through the outer side of the upper portion of the module panel 30 in the vicinity of the rear portion of the door lock mechanism 40, and extends along the outer side of the inner panel 10 behind the module panel 30. extending backwards. After that, the cable 50 bends and changes its direction by about 90 degrees, and extends downward on the outer side of the inner panel 10 . The downwardly extending cable 50 passes through the gap S where the seal portion 60 does not exist, and further extends through the opening (not shown) to the operating portion disposed on the inner side of the door. ing.

The gap S is located between the inner panel 10 and the module panel 30 in the vehicle interior and exterior directions, and here extends in the vehicle front-rear direction. The seal portion 60 does not exist in this gap S. The gap S is arranged at a position through which the cable 50 extending downward after being bent passes. That is, the gap S is positioned downward by a predetermined length and rearward by a predetermined length with respect to the rear upper end portion of the module panel 30 . The length of the gap S is not particularly limited as long as the length allows the pair of cables 50 to pass through.

The seal portion 60 has first to fourth seal portions 61-64. Although not shown, the sealing portion 60 also has a portion that extends continuously from the entire edge of the module panel 30 on the front side of the vehicle to the entire lower edge of the module panel 30 .

The first seal portion 61 extends downward from an upper end portion 61a of the gap S located at the rear of the vehicle. The second seal portion 62 extends downward from an upper end portion 62a of the gap S located in front of the vehicle. The third seal portion 63 continues from the lower end portion 61b of the first seal portion 61, extends to the lower portion of the module panel 30 on the vehicle rear side, and is continuous with the above portion. The fourth seal portion 64 extends continuously from the upper end portion 62a of the second seal portion 62 to the upper portion of the module panel 30 on the rear side of the vehicle.

Here, the first seal portion 61 and the second seal portion 62 extend in parallel in the vertical direction.

Furthermore, the linearly extending portions of the third sealing portion 63 and the fourth sealing portion 64 extend linearly on the same imaginary straight line L. As shown in FIG.

The external shape of the module panel 30 is determined so as to include the thus configured seal portion 60 in a side view. That is, the upper part of the module panel 30 on the vehicle rear side has an oblique side 31 that is located a predetermined distance behind the imaginary straight line L with respect to the vehicle. The oblique side 31 cuts out a portion such as a bent portion of the cable 50 so as not to cover the module panel 30 .

Further, the module panel 30 has an extending portion 32 which extends upward from the intermediate portion of the oblique side 31 and has a side located a predetermined distance to the rear of the vehicle from the first seal portion 61 as a side on the vehicle rear side. have.

Here, the oblique side 31 extends downward toward the rear of the vehicle at an angle of about 45 degrees, and the extending portion 62 has a substantially right-angled triangular shape when viewed from the side. However, the angle of inclination of the oblique side 31 is not particularly limited. is not limited to For example, these oblique sides 31 may not be on the same straight line L but may be shifted, or may have different angles of inclination. Furthermore, these hypotenuses 31 may be curved or bent.

Moreover, the extending portion 32 is not limited to having a substantially right-angled triangular shape when viewed from the side. For example, the upper side of the extending portion 32 in a side view, that is, the portion forming the gap S is not limited to extending horizontally, and may be inclined, curved, or bent. The side of the extending portion 32 on the rear side of the vehicle in a side view is not limited to extending vertically, and may be inclined, curved, or bent.

Moreover, the height of the upper end portion 61a of the first seal portion 61 and the height of the upper end portion 62a of the second seal portion 62 may be the same or different. The heights of the lower end portion 61b of the first seal portion 61 and the lower end portion 62b of the second seal portion 62 may be the same or different.

As described above, in the door structure 100 according to the embodiment of the present invention, it is possible to prevent water splashed up from below the door structure 100 from entering the inside of the vehicle through the gap S. More specifically, when the vehicle is running on a slope, water accumulated in the lower part of the door structure 100 may splash up in the direction indicated by the arrow in FIG. However, in the door structure 100, there are the first seal portion 61 and the second seal portion 62 extending parallel to the vertical direction in the longitudinal direction of the vehicle in the gap S. It is possible to reliably prevent water from directly passing through the gap S by contacting with any of them.

Conventionally, in order to prevent water from passing through the gap S, the position of the gap S is set at a high position, for example, as shown in FIG. It extended to near the upper end of 91. However, according to this, the module panel 91 becomes large.

On the other hand, in the door structure 100 according to the embodiment of the present invention, the gap S can be positioned lower than in the conventional door structure. As a result, the module panel 30 can be miniaturized by reducing the portion located above the gap S. As shown in FIG.

Although the door structure 100 of the embodiment of the present invention has been described above, the present invention is not limited to this.
